QPress – QOM-DIGI 1700 Series
The QOM-DIGI 1700 Series brings a digital interface to compact pressure sensing, returning an I2C signal straight to a microcontroller or embedded board. A stainless 316L wetted section covers 0-0.07 to 0–70 bar plus compound ranges, and an IP67 housing suits damp and washdown spots on equipment and instrumentation. For OEMs building digital control into their products, it removes the analogue-to-digital conversion step and keeps the signal clean from sensor to board.
